If we said the name “Omar Hurricane” to you, you probably immediately think of a man with a giant laser. And, in fact, Omar Hurricane is a man with a giant laser, it’s just that instead of a Bond villain, he’s a researcher at Lawrence Livermore National Laboratory who works with the National Ignition Facility, aka the NIF. He’s also the man who announced that nuclear fusion has been achieved, which means he’s the guy who got to announce what is possibly the most important scientific breakthrough. Yes, as in ever. Here’s what you need to know about nuclear fusion, and why it’s a big deal.

So I have to be a physicist to understand nuclear fusion?

Not to grasp the basic concept: You slam two things together really, really hard.

That’s it?

OK, so it’s slightly more involved than that: Essentially, the idea is to collide two atomic nuclei, in most cases hydrogen atoms, to create a new atomic nucleus, in most cases helium. Essentially you smack them together so hard they turn into something else. This process is so energetic that mass is not conserved but rather some of it is turned into energy, usually photons.

If this sounds familiar, look up. That giant ball of fire in the sky is basically a fusion reactor.

So, what’s the big deal?

In theory, if you can get a nuclear fusion reactor working properly, it would generate more power than you put into it, using the single most abundant element in the entire universe with zero dangerous waste products. It would also ‘feed’ on itself, constantly refueling. In other words, it would end our power problems forever. No more pollution. No more resource wars. Basically we could stop worrying about generating power and focus our resources elsewhere, like space travel.

OK, yeah, that is kind of a big deal. You mean to tell me we can now basically ignite a sun?

Not quite. To get to this point, we had to build a $3 billion laser that fires the length of three football fields at a target the size of pencil and used 500 trillion watts of power. We didn’t get more energy out of the reaction than we used to get the laser going.

But it worked!

Why wasn’t it working before?

Essentially because the hydrogen could get out. Here’s what Omar Hurricane said to NPR on the matter:

Hurricane says researchers now understand why their original strategy wasn’t working. In the journal Nature, he and his colleagues report that they’ve finally figured out how to squeeze the fuel with the lasers. By doing a lot of squeezing right at the start, they were able to keep the fuel from churning and squirting out. The lasers squeezed evenly and the hydrogen turned into helium.

Where do we go from here?

We’ve proved it’s possible, which is the first step. Next, we’ve got to figure out how to make it a self-sustaining reaction, and scale it up to the point where we can get the reactor going. It’s also a valuable insight for fusion researchers elsewhere, whether they’re using lasers or insanely powerful magnets to try and achieve a fusion reaction.

So we won’t be seeing this at home any time soon.

No, but it gives us a lot of hope for the future. And that’s always good.

But a loss-of-coolant accident at a fusion plant would be self limiting — the most likely scenario would be a shutdown with no dangerous radiation products. Even if there was a catastrophic loss scenario, it would be no more dangerous than your average natural gas pipeline explosion. Not something you want to happen, but it’s an easily quantifiable risk that can be dealt with on a purely short term basis — it won’t cause long-term contamination like Fukushima or Chernobyl.

I agree with Eatz, that guy has pre supervillain name written all over him. No one pull his funding or accuse him of having irrational plans that arent feasible. He will try and prove them wrong and then bam, new yorks getting attacked by a Fusion powered Hurricane.

Well since many corporations could unbelievable profits from it you would need one with lots of money and who makes terrible financial decisions (that would describe a wall st bank but still very unlikely).

Before anyone gets their panties in an overly optimistic bunch, the over-unity energy production refers only to the actual watts of laser power delivered to the fuel pellet. It completely avoids discussing the massive inefficiencies in the laser beam generation process so there’s no chance that on a total in/total out basis this thing came anywhere close to unity.
